FC4 Ex (HS) – Supplementary safety information
Batteries for explosion-proof units
Operate explosion-proof units only with the matching and approved
explosion-proof batteries! You can identify the allowed combination of unit
and battery from the lettering on the unit housing. The use of other
batteries which are not expressly approved is strictly forbidden as
otherwise the operating permit of the units in hazardous areas will expire
GB
due to the missing explosion protection and because such a unit
constitutes a safety risk!
Allowed combination:
Explosion-proof units may be operated only with the explosion-proof
battery, part no. 50 1082 8000.
Replacing the batteries
The batteries of the explosion-proof units may be replaced only outside of
the hazardous areas. The company operating the system and the units is
responsible for execution of the battery replacement with the necessary
care and for compliance with the designed safety precautions – in that
case proper screwing-on of the battery with the locking screw.
Batteries must not be separated from the unit in hazardous areas with a
potentially explosive atmosphere.
Charging the batteries
The chargers are not explosion-proof and therefore may be installed
and used only outside of hazardous areas. That is why charging of
the batteries is allowed only outside of hazardous areas, too.
Use only the system-compatible Desktop Charger DC4 Professional with
part no. 50 1080 9200 and the associated plug-in power supply unit with
part no. 59 0060 2814.
The use of other chargers is strictly forbidden since the batteries might
overheat and be damaged.
Use of bags for explosion-proof units with and without a clip
If units with a bag are to be used in hazardous areas with potentially
explosive atmospheres, there are two options:
• Use of an explosion-proof unit with a clip along with a bag, part no.
